CUSTOMER TESTIMONIALS

I would like to give a very big thank you to Dobeck Performance. My bike has never run so well! I've had the Power Commander, and Thunder Junk, oh sorry I mean Max. Don't waste your money. Just buy the EJK EFI tuner and be done! Thanks again DP! Kirk

I bought an EJK GEN 3. The unit installed like a dream and better than that, this unit enabled me to achieve the adjustments to correct the problems I was having. Thanks for delivering just what you said it would do. Also thanks for extending a discount for us vets. George

I selected the Dobeck Performance EJK GEN 3.5 because of the excellent reviews, performance, value, ease of installation and operation. At the time of the EJK install, I also installed a HD Screamin Eagle Stage One air cleaner. The test ride: Whoa!!! This fuel starved, EPA compliant, oversized lawn mower engine was awakened. Out of the box, the annoying/irritating conditions were gone. Cruise at all speeds is very smooth!! This bike is now a pleasure to ride as it should be. Thanks DP. James

TUNING INTERACTIVE DEMO

The following interactive demo should help you understand what each mode adjustment is affecting within a vehicle drive cycle. Please remember the following points for this demo:

The demo is illustrating the most common feature setup for applications. Be sure to understand which features are assigned for your particular controller. The features will be listed in your instructions. They can also be found by navigating to your vehicle in the product section.

The fuel ranges are blown up for illustration purposes. In real applications, slight fuel changes from the stock curve can make a big difference.

Do not assume from the power curve graph that the controller has simply low, mid, and high range fuel adjustments. For illustration purposes the graph shows the natural progression through the zones for one given gear.

A GEN 3 application is displayed where fuel can only be added to the stock curve. GEN 3.5 applications can subtract fuel.

The pictured controller is functional!!Press the Mode, Plus (+), and Minus (-) buttons to make adjustments.
